I think I agree: that Tuple is basically a "data structure" and what you
really want is a representation of the mathematics. I, at least, often
find it difficult to separate the two in my mind, especially in a cae like
this where the mathematics is so close to the data structure. Is it the
cae that you (Joe) want objects such as
[cartesian, X, Y, Z]
[Polar, r, theta, phi]
and so on?
If so, that does look indeed like Intergeo territory - would Paul like to
comment?
